To all/ Z whom it may concern:

Be 1t known that I, HENRY NOEL Forms,

a citizen of the United States, and a resident of New Rochelle, county of Westchester, State of New York, have invented eertain'new and useful Improvements in Ozonizers, of which the following is a specification.

My invention relates to an improved apparatus for obtaining ozone and storing it in a to suitable container or applying it directly to use.

It is found that ozone is developed in -large quantities when electric current is passed through an, inclosing tube or. vessel .15 made of a material which is pervious to the ultra-violet rays. For example, when the tube or container of silica is provided with electrodes inside the tube, one oi. the elec trodes belng ol: some volatilizable material,

such as mercury, and. an electric current is caused to traverse the space betweeathe electrodes, ozone is developed in large quan-' titles in the air'outsideof and about the tube.

Under such conditionsit sometimes becomes 2 5 necessary to protect the operatorsof the apparatus from the efiectsof the ozone, as by surroundingthe apparatus by an ozone contaming vessel of some material which pervious to the ultra-violet rays, such as or- 3 dinaryl lass The c jeet of thepresent invention is to.

provide means whereby the qu'alitiesbelongmg to an apparatus of the character described above may be utilized for developing 3' 5 ozone as set forth, and whereby the ozone do teloped may be collected-for storage or for application tolmmediate use, according to circumstances or requirements.

The present invention consists in surro unding an ozone generator of the kind described,

' with an envelop which is opaque to the ultraviolet rays though not necessarily forxother I we. ve lengths and which preferably presents to j the generator a polished or difiusely reflecting 4.5 surface, and collecting or using'the ozone generated. An inclosing. vessel 0t this sort provided with an air inlet passage and with an outlet passageat its. opposite ends,

. .Jpermits oi the rapid and continuous genera- 5 tlon of ozone and ofits being. conducted to a suitable reservoir or to a pointwhere-it may be d1rectlynt1lized without. being stored.

' understood that means not In some instances, 1 may provide special.-

cooling means, such as a water jacket, around the outside containing vessel, to carry off the excess of heat developed. in' the operation of the ozone generating apparatus. 1 may also cause and the outlet, whereby the development of ozone may be materially increased.

.The apparatus which generates ozone in the air to pass througha zigzag ortortuous path betweenthe lnlet" the manner described may also be a source ot' light, and the devices made use of for storing or applying the ozone may be so constructed and arranged as to interfere very little with the utility of the device as a light giving source;

My invention. will be understood by reference to the accompanying drawings in which Figure 1 is a partly sectional view o1, an apparatus embodying my invention, together with a diagram of the electrical circui ts Fig,

2 is a longitudinal section of a modified form .of apparatus;

and Figs, 3 and 4 are respectively, a longrtudmal and a cross section oi another modification.

Referring to thefirst figure oi the drawings, 1 is a tube of silica, or other medium sufiiciently pervious to ultra-violet radlation, the said. tube containing electrodes, '2 and. 3 which are here represented. as of mercury. One of the said electrodes, say the positive, may be of iron or other solid ma-' terial,and the other of mercury or some othervolatilizable material, but it .isconvcnient torepresent them as being bothcomposed of mercury. Lead-wires, 1 and 5, are connected to the respective electrodes, 2 and 3, through the walls of the tube 1, and the said lead-wires are connected through a suit able switch, 6 ,to a generator, 7 and a. resistance or-reactance device 8. The circuit shown is simply typical of an electric circuit suited for'operating the ap aratus, it being herein illustrated may be utilized for causing an initial flow of current through the ap aratus. Around the tube 1,1 may place a tu loe 9,, of silver, glass or other reflecting material. The tube 9 may be sealed tothe tube 1, as indicated at 11 in Fig. 1". At 12 I show an inlet tube for air or oxygen, and at 13 an outlet tube, which may eX-tendto a reservoir (not shown.) or to a g i k .4 vious to 'ozonizing radiation,

point or points where the ozone is to be-d-irectly uti ized for any suitable purpose. In 0 eration'the :air or oxy n entering .at the tu e 12 is subjected to tile-influence of the ozonizing radiation which traverse the silica tube 1 and is ozonized within the tube 8, the products of ozonization being carried off through the tube 13. T

Fig. 2 re resents a construction generally r0 similar tot at shown in Fig. 1,'b1it-i1i the-de vice illustrated in Fig. 2 the air inlet 12 and the ozone outlet, 13, pass through the ends of the tube Qand-inlet-and outlet pipes or tubes, shown at 14-and' 15, respectively, pass into the l 5. outer walls of the tube-9 which in this instance is shown as a double tube having an annular space, 16, through. which water mayv be caused to circulate for cooling purposes.

In Fig. 3, the interior of the tube 9 and the exterior of the tube 1 are provided with alternate sets, 17 and 18, of rin s, as shown, whereby the air entering the in ct pipe, 12, is caused to pass through a zig-zag or tortuous path between the walls of the respective 2 5 tubes, whereby a. higher degree of ozonizatlon is secured. In this figure and in Fig. 4, I show cooling vanes,'10, consisting of corrugated rings extending outward from the ex- I ter or, of the tube 9. Q'To facilitate the circu- 0 lation of the air or .oxgen through the annular space between the generator and the outer envelop I may employ any suitable pump, fan or other device.
